Does drinking sugar-free cola cause weight gain?
Generally speaking, whether drinking sugar-free cola will cause weight gain depends on the amount consumed. If the consumption is high, it may lead to weight gain; if the amount is small, it generally will not. Detailed analysis is as follows:

When the consumption of sugar-free cola is high, although it does not contain sugar itself, it contains sweeteners such as aspartame and sodium cyclamate, which may have indirect effects on the human body. Excessive intake of these sweeteners may interfere with the body's metabolic mechanisms, especially the metabolism of sugar, thereby leading to weight gain.
If the consumption of sugar-free cola is low, its impact on the body will be relatively limited. When consumed in moderation, the sweeteners in sugar-free cola will not have significant negative effects on the body. Additionally, due to the low consumption level, sugar-free cola generally does not cause weight gain.
In daily life, it is recommended to maintain a balanced diet, consume various nutrients in appropriate amounts, and combine this with suitable physical activity to maintain a healthy weight and physical condition.
